Find the equation of the circle whose center and radius are given.
center (7.-3), radius = 7

(x - 7)² + (y + 3)² = 7

Step-by-step explanation:

The equation of a circle is denoted by: , where is the centre and r is the radius.

Here, the centre is (7, -3), which means and . The radius is r = √7. Plug these values into the formula:

Thus, the answer is (x - 7)² + (y + 3)² = 7.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
